As the others have mentioned, the signal strength is good. The Point Dish screen is very much out of date. It does not take into account any of the newer 1k.2 and 1k.4 dishes. It is based on the old SuperDish, Dish 500, and Dish 300. Those are WA satellites, and changing the direction on the dish to accommodate those satellites will net you no signal more then likely.
Based on your zip, it looks about right. Elevation looks to be 42.4, Azi is 189.4 and skew is 87.5, all in degrees of course. There was likely not a need to change it from the 90, or the signal was better at that angle. This information was found using your zip and
Satellite Finder / Dish Pointing Calculator with Google Maps | DishPointer.com .
With regard to the post, I would add that perhaps the post is not level, which made the 90 degrees work better then the recommended 87.5. Do you know how far the post was driven in? What kind of post was it, a solid steel bar? If there is any concern as to the installation, I would be more then happy to reschedule a tech, but I do not see an issue at this time needing a tech to roll on it, depending only on the answers to the other posters questions and my own.
